RADIATOR-CORE.

Specification of Letters Patent.

Patented May 31, 1921.

Application filed November 1, 1917. Serial No. 199,784.

To all whom it may concern Be it known that I, RUSSELL E. BENNER, a citizen of the United States of America, residing at Flint, in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Radiator- Cores, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to radiators of the type employed in connection with internal combustion engines, and comprises the novel construction of the radiator core as hereinafter set forth.

In the drawings:

Figures 1 and 2 are perspective views of the formed metallic strips which are used in conjunction to form the core;

Fig. 3 is a vertical section through a plurality of strips showing the manner of assembling the same;

Fig. 4 is a vertical section through the assembly;

Fig. 5 is a horizontal section therethrough;

Fig. 6 is a front elevation.

A is a metallic stripg, which is formed with a series of zigzags preferably so as to form two sides of a substantially equilateral triangle.- The apices of the angles are fiattened and at the opposite edges of the strip approach the point of intersection of the angling planes, as indicated at C, while in the central portion of the strip there is a greater flattening and depression, as indicated at D. E isa cooperating strip which is formed with straight marginal edges F and with angular depressions or pockets G, correspondingly spaced to the zigzags in the strip A but of lesser size. The portion H between said angular pockets and intermediate the edges F of the strips is also slightly deflected from the plane of the edges of the strips, as indicated.

In assembling vthe core two strips E are placed together in reverse positions, with their edge portions F in contact. This will leave a space between the portion H, said space being enlar ed by the pockets Gr. Strips A are then p aced upon opposite sides of the strips E with the portions C in contact with the marginal portions F and with the portions D in contact with the portions H. The whole core is built up of series of strips arranged in this order and when dipped all of the contacting surfaces will be soldered to each other so as to make an exceedingly rigid structure, and this structure comprises a series of conduits formed by the air passing through the surrounding aircells. As the strip A has a large contacting surface with the strips E there will be good heat conduction and consequently'all of the surface of both strips will be effective in dissipating the heat.

The construction is one which can be manufactured at small cost, as the strips A .and E may be formed vcontinuously'by a rolling process and may be quickly assembled in relation to each other.

What I claim as my invention is A radiator core, comprising strips each. having straight edge portions in contact with another strip and the portions intermediatesaid edges oifset to form conduits, said intermediate portions being expanded at intervals to form transversely-extending enlarged water-cells, and zigzag fin strips respectively .arranged between said conduits, said fin strips having edge portions between which the contacting edge portions of the water-tube are embraced, and having intermediate portions fashioned to bear upon the conduit strips intermediate the expanded water-cells thereof to form air cells surrounding said water-cells.

In testimony whereof I afiix my signature.
